Claymore's Dual Ethereum + Decred / Siacoin / Lbry / Pascal / Blake2s / Keccak AMD + NVIDIA GPU Miner.=======================Latest version is v15.0 - Supercharged Edition:- now miner supports up to # 384 epoch (4GB DAG size). Note that previous versions support up to # 299 epoch, you will not be able to use old versions after # 299 epoch.- added support for navigation cards (ETH only mode).- now miner sets environment variables automatically (required for 4GB AMD cards).- a few minor bug fixes and improvements.DOWNLOAD LINK: MEGA - Newest Claymore's dual Ethereum AMD + NVIDIA GPU Miner v15.0 (Windows / Linux)version is v14.7 - Supercharged Edition:- now the miner driver does not require switching windows to test mode. If you want to test Mode off, use "-driver uninstall" option (with admin rights) and reboot,then start miner with admin rights to install new driver automatically when necessary (or use "-driver install" option directly).If you have any problem with signed driver you can use "-driver install_test" option, it uses old approach: enables Test Mode (reboot is required) and installs unsigned driver.- added "show power" option for stats about GPU power consumption, press "s to see it. Both AMD and Nvidia cards are supported, except for Linux gpu-pro drivers and Radeon7 cards.- updated Remote Manager to show total power consumption.- fixed issue with "-logsmaxsize" option when "-logfile" option is used to specify directory for log files.- a few minor bug fixes and improvements.version is v14.6 - Supercharged Edition:- now "-rxboost" option also supports old AMD cards (Hawaiian, Tonga, Tahiti, Pitcairn), use "-rxboost 1" to improve up to 5% by applying some additional memory timings ,- now "-rxboost" option supports all AMD drivers.- now "-strap" for AMD cards also supports AMD blockchain drivers.- some changes to further reduce stale shares a bit.- added "-minspeedtime" option.- added statistics for shares accepting time (min / max / average), press "s" to see it.- a few minor bug fixes and improvements.FEATURES:- Supports applying optimized memory timings (straps) on-the-fly in Windows, without flashing VBIOS (currently Polaris, Vega, Nvidia 10xx cards only), up to 20% speedup. Best straps for Ethereum are included.- Supports new "dual mining" mode: both Ethereum and Decred / Siacoin / Lbry / Pascal / Blake2s / Keccak at the same time, with no impact on Ethereum mining speed. Ethereum-only mining mode is supported as well.- Effective Ethereum mining speed is higher by 3-5% because of a completely different miner code - much less invalid and outdated shares, higher GPU load, optimized OpenCL code, optimized assembler kernels.- Supports both AMD and nVidia cards, even mixed.- No DAG files.- Supports all Stratum versions for Ethereum: can be used directly without any proxies with any pools that support eth-proxy, qtminer or miner-proxy.- Supports Ethereum and Siacoin solo mining.- Supports both HTTP and Stratum for Decred.- Supports both HTTP and Stratum for Siacoin.- Supports Stratum for Lbry, Pascal, Blake2s, Keccak.- Supports failover.- Displays detailed mining information and hashrates for every card.- Supports remote monitoring and management.- Supports GPU selection, built-in GPU overclocking features and temperature management.- Supports Ethereum forks (Expanse, etc).- Windows and Linux versions.This version is POOL / SOLO for Ethereum, POOL for Decred, POOL / SOLO for Siacoin, POOL for Lbry, POOL for Pascal, POOL for Blake2s, POOL for Keccak.For old AMD cards, Catalyst (Crimson) 15.12 is required for best performance and compatibility.For AMD 4xx / 5xx cards (Polaris) you can use any recent drivers.4GB cards:GPU_FORCE_64BIT_PTR 0GPU_MAX_HEAP_SIZE 100GPU_USE_SYNC_OBJECTS 1GPU_MAX_ALLOC_PERCENT 100GPU_SINGLE_ALLOC_PERCENT 100This miner is free-to-use, however, current developer fee is 1%, every hour the miner for 36 seconds for developer.For all 2GB cards and 3GB cards devfee is 0%, so on these cards you can mine all ETH forks without devfee, this miner is completely free in this case.If some cards are 2 ... 3GB and some> 3GB, 2 ... 3GB cards still mine for you during devfee time, only cards that have more than 3GB memory will be used for devfee mining. Miner displays appropriate messages during startup.Second coin (Decred / Siacoin / Lbry / Pascal / Blake2s / Keccak) is mined without developer fee.So the developer fee is 0 ... 1%, if you do not agree with the dev fee - do not use this miner, or use "-nofee" option.Miners want to show the same hashrate.Miner can not just stop if cheat is detected because creators of cheats would not know the cheat does not work and they would find new tricks. If miner does not show any errors or slowdowns, they are happy.This version is recent AMD video only: 7xxx, 2xx and 3xx, 2GB or more. Recent nVidia video cards are supported as well.CONFIGURATION FILEYou can use "config.txt" instead of specifying options in command line.If there are not any command line options, miner wants to check "config.txt" file for options.If there is only one option in the command line, it must be configuration file name.If there are two or more options in the command line, you want to use the command line, not from configuration file.Place one option per line, if first character of a line is ";" or "#", this line wants to be ignored.So you can use environment variables in "epools.txt" and "config.txt" files. For example, define "WORKER" environment variable and use it as "% WORKER%" in config.txt or in epools.txt.

For example, define "WORKER" environment variable and use it as "% WORKER%" in config.txt or in epools.txt.So you can select current pool in runtime by pressing "e" or "d" key.REMOTE MONITORING / MANAGEMENTMiner supports remote monitoring / management via JSON protocol over raw TCP / IP sockets. So you can get recent console text lines via HTTP.Start "EthMan.exe" from "Remote management" subfolder (Windows version only).Check built-in help for more information. "API.txt" file contains more details about protocol.KNOWN ISSUESNon-constant mining speed in dual mode, sometimes speed becomes a bit slower. This issue is mostly fixed in recent versions, but not complete.- AMD cards: in Linux with gpu-pro drivers, the list of GPUs may vary from the list of temperatures. You can use -di to change order of GPUs to match both lists.- nVidia cards: dual mode is not as effective as for AMD cards.- Windows 10 Defender recognizes miner as a virus, some antiviruses do the same. Miner is not a virus, add it to Defender exceptions.I write miners since 2014. Most of them are known to be viruses by some paranoid antiviruses, perhaps because of my miners to protect them from disassembling, perhaps because some people include them in their botnets, or these antiviruses are not good, I don 't know. For these years, a lot of people used my miners and nobody confirmed that my miner stole anything or did something bad.Note that I can guarantee clean binaries only for official links to my posts on this forum (bitcointalk). If you downloaded miner from some other link - it really can be a virus.However, my miners are closed-source so they can not prove that they are not viruses. If you think that I write viruses instead of good miners - do not use this miner, or at least use it on systems without any valuable data.TROUBLESHOOTING1. Install Catalyst v15.12 for old AMD cards; for Fury, Polaris and Vega cards use latest blockchain drivers.2. Disable overclocking.3. Set environment variables as described above.4. Set Virtual Memory 16GB or more.5. Reboot computer.6. Check hardware, risers.7. Set some timeout in .bat file before starting miner at system startup (30sec or even a minute), and try "-ethi 4" to check if it is more stable. It can help if it is not stable on some system.FAQ- Miner works too slowly when I mine.Check if you have "Compute Mode" in AMD drivers, so you can press "y" key to turn on "Compute Mode"- I can not mine ETH / ETC with Nvidia 3GB card 10 in WindowsWindows 10 internally allocates about 20% of GPU memory so applications can use only 80% of GPU memory. Use Windows 7 or Linux.
